What Are the Main Industries in Thailand in 2026?
Thailand’s main industries have expanded to now include advanced manufacturing, electronics and electrical appliances, the digital economy and data centres, tourism and hospitality, healthcare and wellness, agriculture and food processing, and financial services.
During the first nine months of 2025, digital industries attracted approximately 626 billion baht in foreign investment, accounting for around 46% of total foreign investment value, largely driven by data centre projects. Electronics and electrical appliances followed with around 271 billion baht (20%), while metals and materials secured approximately 145 billion baht. The figures highlight the continued importance of the Thailand manufacturing industry, while also reflecting the country’s growing role as a regional digital and technology hub.
Foreign investment continues to come from a wide range of markets. Singapore remained the largest source of investment, followed by Hong Kong, China, the United Kingdom and Japan.
To support this growth, the Board of Investment (BOI) continues to refine its investment promotion policies in line with Thailand’s long-term economic strategy. During its December meeting, the BOI announced a series of measures for 2026 and 2027, including the extension of incentives supporting business expansion, company relocations, automotive industry development, advanced manufacturing, joint ventures in automotive parts production, economic recovery initiatives, and community-based investment projects.

Which Industries Does the Thai Government Target for Investment and the New S-Curve Industries
Thailand’s S-Curve industries are a government economic development strategy focusing on a group of targeted sectors to transform the country from a middle-income to a high-income nation.
Through the support and development of the S-Curve Industries, the Government hopes to move Thailand up the value chain by promoting innovation, research and development, and advanced technology in these sectors. It’s part of the broader “Thailand 4.0” economic model launched around 2016 to reduce dependence on traditional manufacturing and low-skilled labor.

In response to changing economic developments and technological advancements, the Thai government has expanded Thailand’s S-Curve industries. The “New S-Curve Industries” now include smart agriculture, electric vehicles, automation systems, data centers supporting artificial intelligence, and wellness and medical services.
Le gouvernement a également introduit de nouvelles sous-catégories dans les domaines de l’IA et de l’automatisation, notamment l’informatique quantique, la robotique avancée et l’IA générative, élargissant ainsi l’éventail des activités éligibles à la promotion du BOI.
For businesses planning to invest in Thailand, the latest BOI measures create new opportunities across some of the country’s fastest-growing sectors. The expanded incentives for 2026 extend eligibility for the standard eight-year corporate income tax exemption to a broader range of AI and technology-related activities, giving early applicants access to support before competition for investment projects intensifies. Complementing these incentives, the government’s “Quick Big Win” initiative aims to strengthen the talent pipeline by developing 100,000 high-skilled workers through reskilling, upskilling, and graduate preparation programmes, ensuring Thailand’s key industries have access to the skilled workforce needed for long-term growth.
Why Are Data Centres and the Digital Economy Booming in Thailand?
The digital economy has become one of Thailand’s most attractive investment sectors, driven by growing global demand for cloud computing, artificial intelligence, cybersecurity, and data storage. It was the country’s largest recipient of foreign direct investment in 2025, supported by the approval of hyperscale data centre projects and major commitments from global technology companies, including Google, AWS, and Microsoft. This momentum has continued into 2026, with the BOI approving seven data centre and data hosting projects at its first board meeting of the year.
The BOI also continues to position Thailand as a regional digital hub by offering attractive incentives for qualifying digital businesses. Depending on the promoted activity, investors may be eligible for corporate income tax exemptions, import duty exemptions on machinery and equipment, and up to 100% foreign ownership, making Thailand an increasingly attractive destination for technology companies looking to invest in Thailand.
For businesses evaluating long-term growth opportunities, digital infrastructure, cloud platforms, AI services, fintech, and enterprise software are expected to remain among the fastest-growing sectors in Thailand’s economy. You can learn more in our guides to data centres in Thailand and fintech in Thailand.
What Is Happening in Thai Manufacturing, EVs and Electronics?
Despite the increased growth within the digital economy, Thailand’s manufacturing industry remains one of the country’s greatest economic strengths. As Southeast Asia’s leading automotive production hub, Thailand is now focusing extensively on electric vehicle (EV) manufacturing. This is highlighted through a series of policy reforms approved by the National EV Policy Board in late 2025. The updated measures place greater emphasis on local production and exports, encouraging manufacturers to expand their manufacturing footprint rather than relying on imported vehicles.
Alongside the automotive transition, Thailand is actively working to strengthen and improve its position in advanced manufacturing. The government introduced a long-term semiconductor strategy in December 2025 aimed at developing a more complete semiconductor value chain, while electronics, the country’s second-largest foreign direct investment sector, continues to support growth across the automotive, energy, data centre, and smart manufacturing industries.
For businesses evaluating the Thailand manufacturing industry and the key industries in Thailand, electric vehicles, semiconductors, smart electronics, robotics, and industrial automation remain among the country’s strongest long-term investment opportunities. Learn more in our guides to Thailand’s EV policy, robotics and automation in Thailand, and smart electronics in Thailand.

How Big Are Tourism, Healthcare and Wellness in Thailand?
Tourism and hospitality remain among the key industries in Thailand, but investment is increasingly being driven by healthcare, medical tourism, and wellness. Thailand has long been considered as one of the world’s leading medical tourism destinations, supported by a network of internationally accredited hospitals, specialist clinics, wellness centres, hotels, and recovery facilities. In 2025, the country’s health tourism market was estimated at approximately THB 670 billion.
Government policy is also encouraging increased investment within these sectors. Hotels may qualify for BOI investment promotion under eligible projects, while healthcare, medical services, and wellness businesses form part of Thailand’s New S-Curve industries, highlighting their importance to the country’s long-term economic strategy.
Combined with growing demand from international patients and Thailand’s aging population, these policies are creating new investment opportunities across healthcare, hospitality, and integrated wellness developments for foreign investors.
Where Should Foreign Investors Locate? The Eastern Economic Corridor
The Eastern Economic Corridor (EEC), comprising Chachoengsao, Chonburi, and Rayong, has become Thailand’s flagship investment zone for advanced industry and export-oriented manufacturing. Developed as part of the Thailand 4.0 strategy, the EEC is designed to support next-generation industries through world-class infrastructure, including deep-sea ports, industrial estates, high-speed rail connections, an expanded airport network, and integrated logistics facilities. Reflecting its importance, the EEC attracted approximately 62% of Thailand’s approved foreign investment value during the first half of 2025.
Many of the fastest-growing industries in Thailand are located within the EEC, including next-generation automotive manufacturing, intelligent electronics, digital technology, biotechnology, advanced agriculture, and high-value medical tourism.
To encourage further investment, the BOI offers enhanced incentives for qualifying projects located within the EEC, including corporate income tax exemptions of up to 15 years for eligible activities, import duty exemptions, permission for up to 100% foreign ownership, matching grants under selected programmes, and a preferential 17% personal income tax rate for qualifying foreign specialists.
For eligible foreign investors, the EEC provides an excellent entry point into the Thai market. Access to established supplier networks, modern infrastructure, and direct access to international shipping routes reduce both setup time and operating costs.
Lex Nova Partners has extensive experience supporting businesses establishing operations in Rayong and Chonburi, assisting with company formation, BOI applications, regulatory compliance, and ongoing legal support. If your project involves relocating personnel or establishing operations in the EEC, our guide to the EEC Visa explains how investment promotion, work authorisation, and business setup work together.
How Can Foreign Investors Enter These Industries in Thailand?
Foreign investors looking to expand into these industries in Thailand have several investment structures and market entry options to consider. A typical investment may require corporate structuring, BOI investment promotion, tax planning, immigration, employment, and ongoing regulatory compliance. At Lex Nova Partners, these services are coordinated under one roof by English and French-speaking professionals, giving foreign investors a single point of contact throughout the investment process.
For most foreign businesses, the first and most important consideration is the Foreign Business Act (FBA). The FBA restricts foreign ownership in approximately 50 categories of business activities and limits foreign shareholding to 49.9% in restricted businesses unless an exemption applies. Many service businesses fall within List 3 of the FBA, while other activities require government approval or remain prohibited altogether.
For qualifying projects, however, BOI promotion provides a practical route to invest in Thailand with significantly fewer restrictions. Depending on the promoted activity, investors may be eligible for up to 100% foreign ownership, corporate income tax exemptions, import duty exemptions on machinery and raw materials, permission to own land for the promoted business, and reduced requirements for supporting visa and work permits for foreign executives and specialists.
Following record investment applications in 2025, processing times have become longer than usual as the BOI manages a larger volume of project applications. Businesses planning operations in 2026 or 2027 should therefore begin their planning early to allow sufficient time for company incorporation, investment promotion, licensing, recruitment, and immigration procedures.

Frequently Asked Questions (FAQ): Key Industries in Thailand
What are the main industries in Thailand?
Thailand’s main industries include automotive manufacturing, electronics and electrical appliances, digital technology, tourism and hospitality, healthcare and wellness, agriculture and food processing, financial services, and renewable energy.
Government policies, particularly through the Board of Investment (BOI), prioritise many of these industries by offering tax incentives and other investment benefits, making them key parts of Thailand’s long-term economic growth.
What is the biggest industry in Thailand?
Manufacturing is Thailand’s largest industry by economic contribution, while tourism remains one of the country’s most important service sectors. Measured by recent investment activity, however, digital industries have become the fastest-growing sector. During 2025, digital projects, led by data centres and cloud infrastructure, attracted approximately 626 billion baht in foreign direct investment, ahead of electronics and electrical appliances. The answer therefore depends on how “biggest” is measured, whether by economic output, employment, or investment value.
What are the best industries to invest in Thailand in 2026?
The best industries to invest in Thailand in 2026 are digital technology, data centres, electronics, electric vehicles, semiconductors, advanced manufacturing, healthcare, medical tourism, renewable energy, and high-value agriculture. These sectors align with the BOI’s investment priorities and Thailand’s S-Curve development strategy. Many also qualify for investment promotion, including corporate income tax exemptions, import duty relief, and other incentives designed to encourage long-term investment in strategically important industries.
Can foreigners own 100% of a company in Thailand?
Yes. Foreigners can own 100% of a company in Thailand through BOI promotion or other specific legal frameworks, depending on the business activity. Outside these exemptions, the Foreign Business Act generally restricts foreign ownership in many sectors and may require Thai majority ownership or a Foreign Business Licence. Choosing the right investment structure is therefore essential before entering the Thai market. Learn more about our Corporate and M&A services and how we assist foreign investors with compliant business structures.
